Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79820, here are decompositions:
- 3 + 79817 = 79820
- 7 + 79813 = 79820
- 19 + 79801 = 79820
- 43 + 79777 = 79820
- 127 + 79693 = 79820
- 151 + 79669 = 79820
- 163 + 79657 = 79820
- 193 + 79627 = 79820
Showing the first eight; more decompositions exist.
